Yoga Nidra is an empowering meditation that starts with relaxation. It systematically changes and cycles through brain wave states, lowering beta and increasing alpha, theta and delta for the better.

Yoga nidra literally changes the ‘fluctuations of the mind’ by slowing down brain wave frequencies. Biological sleep only refreshes the bodymind and cannot promote self-realization like yoga nidra can. Feelings of meditative expansiveness are objective biological facts that can be measured in DNA, neurotransmitters, brain waves and more. The physical body changes as the mind changes.

In the second stage, abdominal breathing produces a rise in the “feel good” neurotransmitter serotonin as shown on EEGs. Alpha, theta, and delta brain waves also increase. (Fumoto, et al., 2004).

The third stage of yoga nidra promotes alpha brain waves. During this stage, mental and emotional balance and mindfulness are the focus. Mindfulness stimulates all 9 functions of the frontal cortex of the brain, promoting memory, concentration, and problem-solving while reducing anxiety and depression.

Intuition and creative solutions are associated with theta, the fourth stage of yoga nidra. Anandamide, the “bliss molecule” inhibits the formation of cancer cells. Yoga nidra is happening when the brain is in delta, yet one remains aware.

In summary, yoga nidra produces low beta, increases and balances alpha and theta, and produces delta. The physical body changes as the mind changes. Yoga nidra literally changes the ‘fluctuations of the mind’ by slowing down brain wave frequencies.

Beta – Oscillates at 13-25 Hz

Beta at 13-15 Hz reflects the conscious, thinking mind and the waking state. It’s required for processing information and for linear thinking. Normal levels of beta are good. Low beta, from 13-15 Hz is associated with the body’s housekeeping duties. High beta, from 15-25 Hz, is linked to stress. Anxiety is produced in abnormally large amplitudes of high beta. High beta is also associated with “monkey mind.” It produces high levels of cortisol and adrenaline and many adverse reactions in your body. Fear and anxiety produce high beta. Many beneficial cellular functions are inhibited. Aging is much faster when your brain is bathed in high beta waves. It’s important to know how to keep beta brain waves in check.

Alpha – Oscillates at 8-13 Hz

Alpha is an optimal state of relaxed alertness. During alpha, all brain wave levels of the mind are integrated by connecting the brain’s higher and lower frequencies. Alpha links the thinking mind of beta with the associative mind of gamma with the lower frequency brain waves, which are theta and delta. This allows a flow of consciousness. The alpha state disappears with negative emotions, like fear. A truly integrated person generates large amplitudes of alpha.

Alpha tunes the brain to peak performance as well as facilitates gene expression for better health. Alpha improves the immune system.

Alpha increases levels of mood-enhancing neurotransmitters such as serotonin.

The synapses in the learning and memory circuits of the brain are enhanced at 10 Hz. The alpha frequency of 10 Hz results in significantly increased synthesis of DNA molecule (Takahashi et al., 1986)

Neurons in the brain’s hippocampus fire in the alpha range (4-12 Hz).

Heart coherence is associated with increased alpha brain wave activity. It is a state in which the interval between heartbeats is regular and constant. It produces “an orderly and harmonious synchronization among various systems in the body such as the heart, respiratory system and blood-pressure rhythms,” as reported by HeartMath. It’s produced by positive emotions such as love and compassion. Negative emotions disrupt heart coherence.

Feelings of meditative expansiveness are objective biological facts that can be measured in DNA, neurotransmitters, brain waves and more.

Theta – Oscillates at 4-8 Hz

Theta is characteristic of light sleep and with day and night dreaming. It is the dominant frequency of healers and people in highly creative states. Theta increases in people under hypnosis or in trances. (Kershaw & Wade, 2012).

Theta waves are found during DNA repair. It increases the activity of antioxidants.

Human cartilage cells are regenerated at the 6.4 Hz frequency.

Delta Brain Waves – Oscillates at 0-4 Hz

Delta is characteristic of deep, dreamless sleep. High amplitudes of delta are found in people who are in touch with nonlocal mind, even when they’re wide awake. Meditators, intuitives, and healers have much more delta than normal.

When our brains are producing delta, we are enriching our cells in a frequency that has the potential to produce a whole gamut of beneficial physiological changes at the level of our cells, from growing our telomeres and boosting GH levels to regenerating our neurons and sweeping our brains clear of beta-amyloid plaques. This is what happens during yoga nidra.

Growth hormone secretion is at its highest when delta waves peak in the brain. Growth hormone repairs and regenerates cells. It is associated with the immune system, bone mineralization, muscle mass, fat breakdown and protein synthesis, growth and regeneration of all internal organs and homeostasis.

Ahmed and Wieraszko (2008) took slices of the brain that governs memory and learning. They found that a very low delta band, 0.16 Hz, increases activity in the synaptic connections between neurons in the hippocampus. This suggests that memory and learning may be enhanced by delta activity.

Beta-amyloids are sticky plaques between neurons in the brain, characteristic of Alzheimer’s disease (Kang et al., 2009). They found that during sleep, when brains are primarily in theta and delta brain wave states, beta-amyloid production in the brain stops, and toxic material is cleared away. The effect was even greater during the delta brain wave state.

The ends of chromosomes have stretches of DNA called telomeres. Telomeres protect our genetic data, cause cells to divide, and slow aging. Telomeres normally shorten each time a cell divides. The resonant peaks for 10 telomere sequences clustered around a frequency window of 0.19 Hz and 0.37 Hz (delta). Other frequencies did not affect telomerase (Cosic, et al., 2015). Meditation preserves and increases telomere length.

Delta brain waves are seen on EEGs when people are having a sense of connection with the infinite.

Anandamide, the “bliss molecule” inhibits the formation of cancer cells.

Gamma – Oscillates at 25-100 Hz

Gamma is associated with the integration of information from all the brain’s regions, as well as with coherence as they all synchronize (Gray, 1997). It’s associated with flashes of insight, performing difficult tasks perfectly. Meditation increases gamma.

At the gamma frequency of 40 Hz, beta-amyloid decreased by half. zHz

At 50 Hz, results in the body increasing its production of stem cells, the “blank cells” that differentiate into muscle, bone, skin, or whatever other specialized cells are required (Ardeshirylajimi, & Soleimani, 2015).

At 60 Hz, expression of stress genes (cortisol) is regulated.

A frequency of 75 Hz is epigenetic, triggering the genes that produce anti-inflammatory proteins in the body (De Girolamo et al., 2013).

Alternate nostril breathing, also called Nadi Shodhana or Nadi Suddhi, creates a sense of physical, mental, and emotional well-being. It is done by alternating nostrils while breathing. Doing so balances right and left-brain integration, promotes mental clarity, and whole brain functioning. It can relieve headaches and sinus problems. It calms emotions and fosters feelings of deep inner contentment and balance. Due to its soothing effect, it is ideal preparation for deep relaxation or meditation.

The nadis (pronounced NAH-deez) are the non-physical nerve channels within the body. The nadis deliver prana, the life force, throughout the body. While there are thought to be over 72,000 nadis that travel throughout the body, there are three primary ones that run along the spine. Alternate nostril breathing balances these nadis.

The ida (pronounced EE-dah) is energetically to the left of the spine and is activated by the exhalation. It is associated with the receptiveness, intuition, and passivity.

The pingala (pronounced pin-GAH-lah) is activated by the inhalation and is energetically on the right. It is associated with activity, logic, and objectiveness.

The sushumna (pronounced sue-SHOOM-nah) is the central channel. It is activated by the gap between breaths. It is linked with wisdom and the balancing of our active and receptive nature.

The first step to the practice is to learn the proper hand position to aid in the alternation of the breath. Two hand positions (mudras) are offered. Both are effective. Try them both to find out which feels easier for you. Take a few minutes to get used to switching between nostrils with the hand positions before adding the breathing patterns.

Vishnu Mudra

The first way, named Vishnu Mudra, is to take your right hand and bend your index and middle fingers toward the palm. Your thumb, ring, and pinky fingers are upright. Next, get used to gently closing your right nostril first with your thumb, and then release the thumb and close your left nostril with the ring finger of your right hand. Switch back and forth until it feels smooth.

Nasagra Mudra

Nasagra Mudra is another hand position that can be used. Begin by making the peace sign with your right hand. Next, bring your pointer and middle fingers together and then release your thumb. Place the pads of your index and middle fingers in the center of your forehead or between your eyebrows and then use your thumb and the knuckle of your ring finger to alternately close and release your nostrils.

The rhythm of the inhalation to the exhalation is usually uneven at first. With practice, it will smooth out so they become equal in length. When this is easy for you, begin slowing the exhalation down so that it becomes longer than the inhalation until eventually the exhalation is about twice as long as your inhalation. More breathing ratios are below. Maintain alertness of your breath instead of breathing mechanically.

Process

While either hand position can be used, the Vishnu Mudra is used to describe the pattern for the sake of clarity. The pattern alternates nostrils after each inhalation like this: Exhale – inhale / change nostril / exhale – inhale / change nostril, etc.

Here’s how to practice one round of alternate nostril breathing:

Come into a comfortable seated position with your spine erect.

Form your fingers of your right hand into Vishnu Mudra by curling your index and middle fingers into your palm, straighten the ring and little fingers, and place your thumb against your right nostril. 1. Gently exhale and then inhale through your left nostril. 2. Close the left nostril with the ring finger. 3. Release the thumb. Gently exhale and then inhale through the right nostril. 4. Close that nostril with the thumb and continue with step 1.

In other words, repetition is done by alternating nostrils after each inhalation.

Begin practicing for two minutes and gradually, very gradually, increase to ten minutes. Avoid strain or force.

Breathing Ratio Variations for alternate nostril breathing: Take your time with these ratios. Never rush. Do not force or strain. Do not use breath retention if you have hypertension or other cardiac conditions.

The examples given are to the count of 4. This can be adjusted to 3, 4, 5 or 6 depending upon your comfort level. Count by silently saying Om 1, Om 2, Om 3, Om 4, etc.

Ratio of 1:1 – Develop breath control so that the inhalation and the exhalation are exactly the same length of time. Inhale for the count of 4. Exhale for 4. . Do not proceed until perfected.

Ratio of 1:2 – Double the length of the exhalation. Inhale for the count of 4. Exhale for 8. Do not proceed until perfected.

Ratio of 1:2:2 – Addition of breath retention. Inhale to the count of 4. Hold the breath for 8. Exhale for 8. Do not proceed until perfected.

Ratio of 1:4:2 – Inhale to the count of 4. Hold 16. Exhale 8. Do not proceed until perfected.

The Hakini Mudra for brain-body balance, problem-solving and focus is one of my favorite hand mudras. It’s very effective and easy to do.

Mudras are yoga positions, gestures, and seals for your hands and fingers that facilitate health, healing, psychological balance and spiritual transformation. Some mudras use the whole body and breath. They are effective, easy to learn, practical and powerful, and anyone can do them. Learn more about mudras here.

Hakini Mudra Benefits:

Directs the breath, awareness, and energy to the entire body to balance the bodymind physically and energetically

Complete and full breathing is facilitated effortlessly

Reduces stress

The first six energy centers (chakras) are stimulated and harmonized

Both hemispheres of the brain are integrated and invigorated

Boosts memory, concentration, and assists problem solving

How to do Hakini Mudra:

Gently touch the fingertips and thumb of one hand to the corresponding fingertips and thumb on the other

Hold your palms apart as if you were holding a ball

Place your hands in front of your solar plexus (mid-section)

If your fingernails are too long to touch the fingertips together, interlace all the fingers, separate your palms, and touch the tips of the thumbs together

Many thanks to Dan Leven for sharing this Loving Kindness Face Lift. He was inspired by Sharon Salzberg’s book, Real Love.

As he puts it, “It begins with “may my face be happy, may my face be peaceful.” And then you continue moving through each body part wishing them well in this way… “may my neck be happy, may my neck be peaceful … may my shoulders be happy, may my shoulders be peaceful,” and so on. You open your heart’s kindness to your whole body (including to your own heart).”

It’s a great way to start and end the day. I love it. I really go to town with spreading happiness and peace throughout my entire body. I enjoy coming up with new places to shower with loving kindness with each practice such as for my brain, blood, eyes and ears – even my hair. Before long, it’s going out to family, friends, pets, strangers and to all kinds of situations. This meditation is especially handy when my attention is restless since it lets me jump all around. It can be any length too – long or short. It sure feels uplifting.

Dan goes on to explain the science underpinning it. He says, “the vagus nerve is a core part of our parasympathetic nervous system that has two branches. One branch is associated with surviving in a perceived life or death situation where our whole body slows down, feigning death (a primitive survival mechanism). The other branch is about helping us relax and soften into the loving support of others and is associated with the release of oxytocin (the cuddle or bonding molecule). Both branches are about our relationship to “others”: dangerous “others” or safe and loving “others.”

Here’s the kicker he reports, “the vagus nerve has many fibers that connect to our facial muscles where we reveal our emotions through a plenitude of expressions. Scientists have logged 21 different emotional expressions that register within the face and there are 8 universal emotional facial expressions that you don’t need a translator to interpret. So our face can register the vagal response from shock and terror, like a deer in the headlights of a moving car (survival vagus nerve), to happiness and peace, like a contented Buddha face (loving vagus nerve)! However, we can also create the response as we bring happiness and peace to our faces!”

So the KEY point, according to Dan, “is that as you invite or train your facial muscles to discover happiness and peace you are strengthening the relaxation response that’s linked to feeling supportive or loving connection with others -to feeling safe in the world.”
